Reproduction

Also, repro.

from Fancyclopedia 2 ca. 1959
The making of more than one copy of a publication; the means used in doing so. (That's the meaning we're going to define, at all events.) As our chief method of communication is the fanzine, methods of producing these are an important fannish concern. Standard methods are mimeoing, dittoing, hektoing, and lithography, supremacy passing historically from letterpress-printing to hektoing to mimeography as fandom's ingenuity and size varied. Great resourcefulness has been displayed in discovering new and unusual means of duplication; they include linoblock, silkscreening, rubber stamp, photography, photo-offset, blueprint, and even teletype tape, dog-tag printer, and sonodisc. And some fanzines, like Bill Rotsler's letter-substitutes, are not really duplicated at all, but merely passed around or displayed in the original typescript or as carbon copies.

Standard methods are hektoing, mimeoing, and printing, supremacy passing historically from printing to hektoing to mimeoing, as fandom's size fluctuated. Great ingenuity has been displayed in discovering new and unusual means of duplication; they include linoblock, silkscreening, rubber stamp, fotografy, foto-offset, blueprint, and even teletype tape, dogtag printer, and sonodisc. Some fanzines are not duplicated but merely passed around or displayed, and a few have been carbon copied.
